Beit known that 1, JOHN DANIEL GREEN, of Toledo, Lucas county, Ohio,have invented certain new and useful Improvements in Railway Frogs,Switches, and Guard-Rail Blocks, of which the following is aspecification.

My invention relates to improvements in blocking railway tracks atintersections, crossings, and switches, by which all danger tooperatives of railway companies is removed. 7 I p In the accompanyingdrawings:-Figure 1, is a plan showing a section of railway track, at thelocation of a switch, outlining the rail the guard rails, switchintersection or frog, rails and switch points. Fig. 2, is an enlarged Uportion of Fig.1 showing the frog with my improved blocks in position.Fig. 3, is an enlarged portion of Fig. 1 showing the switch rail andpointwith myimproved block in position. Fig. 4, is a perspective view.of my improved block as adapted to the ends of the railway frog. Fig.5, is a perspective view of my improved block as adapted for use atguard rails and the wings of railway frogs. Figs. 6, 7, and 8, are crosssections of the top plates of myimproved block showing construction asto surface and groovesas adapted for the different positions of theblock. Fig. 9 is a longitudinal vertical section of Fig. 4. Fig. 10, isa longitudinal vertical section of Fig. 5. Fig. 11, is a transversevertical section of my improved block as in position between the railsof afrog. Fig. 12, is a section of a porti on of a rail showing anothermethod of securing my improved blocks to the rail.

In the drawings 1 represents the rails of the main track.

2, is the rails of the siding.

3, is the switch rails.

4, is the switch points.

5, is the rail intersection or frog of which 6 is the point; 7, thewings noted as right 3 and left, 8, the male end and 9 the female end ofthe frog.

10, are guard rails found in railway construction at frogs, crossings,bridges and other places of the necessary.

11, is my improved block as used in the opposite ends of the railwayfrog.

intersections, track, where '12, is .my improved block as used in theWingsof a frog andfor the end of all guard rails. I

13, is my improved block as used at switch points.

14, is the top plate and 15, the bottom plate of 11 and 13.

16, is' the door movably joined to 14 and slanting downwardly to contactwith15.

17, is the top plate and 18 the bottom plate of my improved block asadapted to guard rails and the wings of a frog.

19, is the groove made in the. top plate adapting them tothe shape ofthe rail and allowing them to fit up to them.

20, is an additional groove made in top plate, where needed, to adaptthe plate to use with rails where the flange of the car wheels pass.

21, are the springs placed between the top and bottom plates, allowing adepression of the top plate, where and when necessary, and causing it toresume its position.

22, are the retaining bolts holding the top and bottom plates together,and secured to the bottom plate by nuts 23, having its upper end or headsecured in a cup 24, fastened to the upper plate, admitting of a freemovement when the upper plate is depressed.

23, are nuts or other suitable means of rigidly fastening the bolts 22to the bottom plate.

.24, is a cup or yoke secured to the top plate or integral therewith,engaging the bolt 22 below the head and permitting of a free movement ofthe top plates while in action and preserving all the parts in workingorder below the top surface.

25, are ridges or cup like raises on the surface of the top and bottomplate to retain the end of spring 21 in position.

26, is the end of the bottom plate of the guard rail block turned upforming a retaining wall for the end of top plate 17.

27, is a slot or similar opening in the plate 17. w

28, is the tongue on the end of the bottom plate 18 at 26, and when theguard rail block 12 is put together is driven or bent over through theslot 27, thereby securing the end of the plate 17 and permitting of amovement of the same.

29, is a projecting ear of the bottom plate of the blocks formed orcurved to fit up against the web of the rail, and through both of whicha bolt is secured, thereby fastening the bottom plate of the block tothe rail and securely holding the block in position.

30, is a strap passing under the T-rail with its end bent up engagingthe flange or foot of the rail, a bolt. 31, passing through it andbottom plate of the block securely clamping the block in position, andby passing the bolt 31 through a notch in'the edge of the flange or footof the rail, as shown in Fig. 12, securely holding the block in positionlaterally and from c'reeping.

In the frog block 11, and switch block 13, the outer end or door 16 ispreferably hinged to the top plates, so when the top plates aredepressed the door 16 following creeps outwardly and, when the platesresume normal position, the door 16 follows into place, thereby formingan effective protecting end to the block, protecting the inner orworking parts from dirt or other accumulations. In the wing or guardrail blocks the top plate is formed with the side 32 to it, protectingthe side away from the rails from dirt and other accumulations.

In Fig. 2, the frog block 11, as shown in position at the female end ofthe frog, will have a top plate formed as in Fig. 7, with the grooves 19fitting the ball of the rail, and the flange groove 20,to allow theflange of the car wheels to pass. Top plate of the wing or guard railblocks is formed as in Fig. 8 and as shown in Fig. 5 with the grooves 19fitting the ball of the rail and curved end of the guard rail and havingthe groove 20 formed in the side next to the track rail permitting theflange of the car wheels to pass.

In Fig. 3, is shown the switch block 13 having its top plate formed asin Fig. 8 with grooves 19 fitting the ball of the rail and switch rail,and with grooves 20 formed on the side next the track rail to allow theflange of the car wheel to pass.

In Fig. 3 the switch rail is shown open and track in action with switchrail as closed in dotted lines.

When in position the switch block 13 is switch rail is open and thetrack rail is in action.

In the drawings the track blocks are shown with single springs but theymay be formed with two or more springs placed either laterally orlongitudinally.

I am aware that railway blocks have been in use prior to my invention,and I do not claim broadly such an idea, butI am not aware that theconstruction shown has ever been used, and I am desirous of obtainingthe following claims.

What I claim to secure by Letters Patent, is-

1. In a railway frog, switch, and guard ra1l block a top plate,preferably'of sheet metal, with a groove 19 on one or both of its edges,and a groove 20 on one or both of its edges substantially as, and for,the purpose shown.

2. Top and bottom plates in combinatlon with a compression springinterposed between them and by which they are held apart, a sleevesecured on the inner side of one plate and perpendicular thereto, and abolt projecting from the inner side of said other plate and movable inthe sleeve.

3. Top plate with grooves 19 and 2Q,bottom plate movable door 16 incombination with springs 21, bolts 22,and cup 24, substantially asshown. 1

' 4:. The top plate 17, bottom plate 18, s de 32, in combination withend 26 and fastening 27 and 28, substantially as shown.

5. The top plate 17, bottom plate 18,1n com bination, with end 26 andfastening 27 and 28 substantially as shown.

6. Top and bottom plates in combination with ear 29, substantially asshown.

7. Top and bottom plates in comb nation with straps 30 and bolt 31substantially as shown.

8. The combination of a base plate, a top plate yieldingly mountedthereon, a sleeve on the inner side of one of said plates and a boltbetween the plates and movable in the sleeve to a limited extent, saidbolt being secured to said other plate whereby said plates are connectedtogether.
